Inventor: AKASHI AKIRA
IPC: G03B3/00
Filed: 1987-01-12
Abstract: PURPOSE:To improve the operability of the titled device especially at the time of mounting a telephoto lens by driving a lens immediately when a defocused value after the detection of a focus is < a prescribed value, and when the defocused value is >= the prescribed value, inhibiting the lens driving.

Filed: 1982-01-13
Abstract: PURPOSE:To improve discharge characteristics in a battery and dispersion thereof, by injecting an alkaline electrolyte inside a sealing base plate twice apart before and after charging a mixture of amalgamated zinc dust and a gelling agent. CONSTITUTION:Part of an alkaline electrolyte is injected inside a sealing base plate 7 and, after charging a mixture of amalgamated zinc dust and a gelling agent, the rest electrolyte is further injected into the said mixture, making up a gell-like zinc cathode 6. In the conventional method that the alkaline electrolyte is added after a mixture of the amalgamated zinc dust and the gelling agent is charged, the osmosis of the electrolyte into mixture is not good whereby a state of uniform dispersion inside the mixture of the electrolyte can be no longer expected and likewise, there where some problems so far that a utilization factor of zinc active matter comes down and, what is worse, dispersion in the battery characteristic grows large anyway. Like this method, the alkaline electrolyte is separately injected twice so that these problems mentioned above were all improved.

Abstract: PURPOSE:To ensure a zero detected current when a chip temperature is lower than a specified value and to generate an approximately linear detected current at or above the specified value, by connecting first and second current mirror circuits to temperature detecting transistors. CONSTITUTION:A collector current i2 of a transistor 16 in a temperature detecting part 3, which is controlled by a reference voltage generating circuit 2, is changed with a temperature.

When the current i2 is smaller than an output current I3 of the circuit 5, a current i4 to a second current mirror circuit 6, which is connected to the output side of the circuit 5, becomes zero, and an output current i5 of the circuit 6 becomes zero. Meanwhile, when the temperature is increased and the current i2 becomes larger than the current I3, a current (i2-I3) is applied, and the current i5, which is changed approximately linearly, is outputted from the circuit 6. When a chip temperature is lower than a specified value, the detected current becomes zero without fail. When the temperature is at or above the specified value, the temperature detection current, which is changed approximately linearly, is obtained.
